Idk

Idk is a mono-blue Commander spellslinger/control deck, likely built around Talrand, Sky Summoner.

It aims to play at instant speed with lots of counterspells, card draw, and cheap interaction like Counterspell, Negate, Make Disappear, Opt, and Rapid Hybridization. The main synergy is casting instants and sorceries to generate value from Talrand and Murmuring Mystic, creating flying token armies while controlling the board.

The deck generally wins by slowing opponents down, drawing through its deck, and then overwhelming the table with Drake and Bird tokens from repeated spellcasting. Ramp pieces like Sol Ring, Arcane Signet, and Commander's Sphere help it keep mana open for reactive play.
